Italian High Renaissance Painter and Inventor, 1452-1519 Italian High Renaissance Painter and Inventor, 1452-1519 Florentine Renaissance man, genius, artist in all media, architect, military engineer. Possibly the most brilliantly creative man in European history, he advertised himself, first of all, as a military engineer. In a famous letter dated about 1481 to Ludovico Sforza, of which a copy survives in the Codice Atlantico in Milan, Leonardo asks for employment in that capacity. He had plans for bridges, very light and strong, and plans for destroying those of the enemy. He knew how to cut off water to besieged fortifications, and how to construct bridges, mantlets, scaling ladders, and other instruments. He designed cannon, very convenient and easy of transport, designed to fire small stones, almost in the manner of hail??grape- or case-shot (see ammunition, artillery). He offered cannon of very beautiful and useful shapes, quite different from those in common use and, where it is not possible to employ cannon ?? catapults, mangonels and trabocchi and other engines of wonderful efficacy not in general use. And he said he made armoured cars, safe and unassailable, which will enter the serried ranks of the enemy with their artillery ?? and behind them the infantry will be able to follow quite unharmed, and without any opposition. He also offered to design ships which can resist the fire of all the heaviest cannon, and powder and smoke. The large number of surviving drawings and notes on military art show that Leonardo claims were not without foundation, although most date from after the Sforza letter. Most of the drawings, including giant crossbows (see bows), appear to be improvements on existing machines rather than new inventions. One exception is the drawing of a tank dating from 1485-8 now in the British Museum??a flattened cone, propelled from inside by crankshafts, firing guns. Another design in the British Museum, for a machine with scythes revolving in the horizontal plane, dismembering bodies as it goes, is gruesomely fanciful. Most of the other drawings are in the Codice Atlantico in Milan but some are in the Royal Libraries at Windsor and Turin, in Venice, or the Louvre and the École des Beaux Arts in Paris. Two ingenious machines for continuously firing arrows, machine-gun style, powered by a treadmill are shown in the Codice Atlantico. A number of other sketches of bridges, water pumps, and canals could be for military or civil purposes: dual use technology. Leonardo lived at a time when the first artillery fortifications were appearing and the Codice Atlantico contains sketches of ingenious fortifications combining bastions, round towers, and truncated cones. Models constructed from the drawings and photographed in Calvi works reveal forts which would have looked strikingly modern in the 19th century, and might even feature in science fiction films today. On 18 August 1502 Cesare Borgia appointed Leonardo as his Military Engineer General, although no known building by Leonardo exists. Leonardo was also fascinated by flight. Thirteen pages with drawings for man-powered aeroplanes survive and there is one design for a helicoidal helicopter. Leonardo later realized the inadequacy of the power a man could generate and turned his attention to aerofoils. Had his enormous abilities been concentrated on one thing, he might have invented the modern glider.   Related Paintings of LEONARDO da Vinci :. | The Virgin of the rocks | The Madonna of the Carnation (detail) dg | Annunciation (detail) ey79 | Saint jean-Baptiste | The Last Supper (detail) sg |

ANDREA DA MURANO
Italian painter, Venetian school (known 1462-1502) Italian painter. He is first recorded working as a gilder at S Zaccaria, Venice, in 1463-5. He was one of a number of artists from the island of Murano. Among these he is closest to Bartolomeo Vivarini, whose pupil he may have been. The two collaborated in 1468 on a narrative canvas (destr.) for the Scuola di S Marco, Venice, which probably depicted scenes from the Life of Abraham. The rather harsh sculptural quality of his forms owes much to the influence of Mantegna and Donatello in Padua, and his work has often been associated (and sometimes confused) with that of Andrea del Castagno. He did not, however, ignore the more recent developments of Giovanni Bellini. His triptych depicting SS Vincent Ferrer, Roch, Sebastian and Peter Martyr, with a lunette of the Madonna of Mercy and Four Saints (Venice, Accad.), probably painted in the late 1470s, shows a real concern with light and colour. By the mid-1480s Andrea had settled in Castelfranco on the mainland, chiefly painting altarpieces in the (by then well established) Venetian sacra conversazione form. The altarpiece (1484-1502) in the parish church at Trebaseleghe, nr Padua, is a variation on the form, with Christ embracing the plague saints Sebastian and Roch above and other saints and musicians below, all showing the high degree of expression characteristic of his works. It is one of his finest paintings and also perhaps the most expensive Venetian altarpiece of its day. The altarpiece depicting the Virgin Enthroned with SS Peter, Nicholas of Bari, John the Baptist and Paul (1502; Mussolente, Santuario della Madonna dell' Acqua) is typical of Andrea's work and shows both the strengths and limitations of his art: firm draughtsmanship and expressive qualities combined with a rather conservative composition and somewhat ungainly figures.
